Want royal wedding news? Go right to the source. The building that is the official source of the royal wedding has a Twitter account. At the time of our publication, there had been 695 tweets. They've included information on the commissioned royal wedding anthem and the Abbey's royal wedding app. Even better: More insider news might leak out from wedding guests themselves on Friday. Contrary to rumors, signals won't be blocked, and tweeting will be allowed inside Westminster Abbey during the ceremony. (Paul Ellis / AFP / Getty Images)
